Dynamically Load Formulas Into Cells

Frequently a developer needs to insert formulas into a VBA generated worksheet. If you are loading data into a target worksheet, sometimes the target worksheet can be pre-formatted with formulas. But in many cases - especially when the number of rows vary - you should insert formulas at the time the target worksheet is being constructed. There are basically four ways to do this as the following examples illustrate:

  1. Insert a formula using R1C1 notation with no absolute row or column references using offsets:
    Cells(2, 2).FormulaR1C1 = "=RC[-1] * R[-1]C"
    The resulting formula when viewed in the worksheet is: =A2 * B1
  2. Insert a formula using R1C1 notation with absolute row or column references:
    Cells(2, 2).FormulaR1C1 = "=RC1 * R1C"
    The resulting formula when viewed in the worksheet is: =$A2 * B$1
  3. Insert a formula using standard Column/Row references with no absolutes:
    Cells(2, 2).Formula = "=A2*B1"
  4. Insert a formula using standard Column/Row references with absolute row/column references:
    Cells(2, 2).Formula = "=$A2*B$1"
The code snippet below illustrates how you can dynamically specify the formula string based on variables. This code is not a complete program, but an illustration from sections of a working Excel program that builds formulas using variables.
